You should be ok but be aware of new buds with this early spring again. It is best pruned before the leaves begin to appear so things look good. I might be tempted to leave it for a year.
Late winter (February) or early spring (March) for pruning.
Check the root ball as I would put it in a bigger pot. (not a huge one, just bigger)
